Comparative Study Of Nutrient Uptake Between Sorghum X Drummond Ii And Cyperus Conglomeratus, A Desert Sedge Native To The Uae, Safaa Alm1ed Alghasyah Aldhanhani
Comparative Study Of Nutrient Uptake Between Sorghum X Drummond Ii And Cyperus Conglomeratus, A Desert Sedge Native To The Uae, Safaa Alm1ed Alghasyah Aldhanhani
Theses
Sudan grass (Sorghum x drummondii) is commonly grown for the production of animal fodder in the UAE. Cyperus conglomeratus (locally termed ‘Thenda’) is a sedge native to the UAE, and one of the very few plants that colonize soils of shifting desert dunes. The native plant is grazed by camels, and may thus have a potential for animal feed production. While Sudan grass is a mycotrophic plant that normally lives in symbiosis with arbuscular mycorrhizal fungi for facilitation of nutrient uptake, C. conglomeratus is a non-host to these root symbionts. In the desert sedges rhizosheaths comprising of dense coats of …
Effect Of Substrates, Iba And Types Of Cuttings On Rooting, Salim Mohammed Ai Makhmari
Effect Of Substrates, Iba And Types Of Cuttings On Rooting, Salim Mohammed Ai Makhmari
Theses
Tamarix aphylla L. (Locally known as Athel) was selected for the present investigation. It is native to Middle East (which include UAE), North Africa and south Asia. The tree is drought, heat and salt tolerant. It has some traditional uses. The research leading to standardize the propagation of Tamarix aphylla L. is very rare and therefore it is not widely exploited in the urban landscaping. The present study was aimed to standardize the methodology and substrate for rapid propagation of Tamarix aphylla L. tree. The parameters studied were morphological growth parameters, chemical content, biochemical constituents and antioxidant enzymes activities in …
Examining The Growth And Performance Of The Effect Of Uv-B Radiation On United Arab Emirates Date Palm Tree (Phoenix Dactylifera), Saeedallah Abdulwali Niazwali
Examining The Growth And Performance Of The Effect Of Uv-B Radiation On United Arab Emirates Date Palm Tree (Phoenix Dactylifera), Saeedallah Abdulwali Niazwali
Theses
The stratospheric ozone depletion and elevated solar UV-B radiation have a negative effect on living life forms. UV radiation is one of the unsafe components that cause hindrance to both flora and fauna on the earth. This will have important implications for ecosystem processes and food production. The present study has been designed with primary objective of the effect of UV-B radiation on five numbers of most cultivated Emirates varieties (i.e., BARHI, FRDWT, NBTSF, FRDRD and KHD). After 4 and 8 hrs/day UVB treatment the Shoot, Root and total Plant length, Total plant fresh weight, Shoot and Root fresh and …
Biological Efficiency Of Recycling Organic Waste With Edible Fungi, Yusra Matar Al Shamsi
Biological Efficiency Of Recycling Organic Waste With Edible Fungi, Yusra Matar Al Shamsi
Theses
Mushrooms has been known as important cultivars for their nutritional and medicinal values, the species Pleurotus sajor caju and Calocybe indica were selected in this investigation for being used in previous studies to be grown on different lignocellulosic materials. Cultivating mushrooms on plant wastes is value-added way to produce a source of human food and is an efficient way to recycle those residues. Date palm leaf waste, date palm bunch waste and mowed turf grass waste were used as mushroom growing substrates. Date palm is the most important plant grown in the UAE and it produce tons of wastes every …
In Vitro Re Generation And Marker Assisted Evaluation Of Genetic Fidelity In Endangered Tree Species Moringa Peregrina (Forsk) Fiori, Salama Mohammed Al Dhaberi
In Vitro Re Generation And Marker Assisted Evaluation Of Genetic Fidelity In Endangered Tree Species Moringa Peregrina (Forsk) Fiori, Salama Mohammed Al Dhaberi
Theses
Moringa peregrina is a native plant in the United Arab Emirates; it is called “Shua”.It is an endangered species with important nutritive and medicinal properties. It shows high adaptability to the arid condition with short germination time after irrigation. Unmanaged grazing and slow regeneration rate after browsing leads to the endangerment of the species causing erosion in biodiversity. One way to protect these rare species is by multiplying the planting material through tissue culture system and re-introducing at the habitat. Micro propagation is an in vitro method used for plant clonal multiplication under controlled condition. This technique allows conserving the …

Exploration And Implementation Of Innovative Efficiencies/Devices In Beet Processing For Energy Production, Patrick Mcinerney
Theses
The imminent depletion of fossil fuels, as well as concerns for energy security and the obligation to respond to climate change has led to expanding worldwide popularity of Anaerobic Digestion (AD) of energy crops. Sugar beet is a popular AD feedstock due to its favourable characteristics; however it can be quite labour intensive requiring a range of specialist equipment to process the crop prior to undergoing AD. A crucial stage of this process involves the size reduction of beet by a mechanical chopper unit; this pretreatment breaks open the cellulose structure of the crop and increases the surface area available …
An Investigation Of The Use Of Natural Agents To Control Mycobacteria, Olga Lesniak
An Investigation Of The Use Of Natural Agents To Control Mycobacteria, Olga Lesniak
Theses
Economic losses that are caused by Mycobacterium avium paratuberculosis (MAP) infections represent a major obstacle for farmers and also for the dairy industry. In order to control the population of MAP, alternative control agents must be investigated. One of the studies described in this thesis focused on using a bacteriophage therapy based approach to assess its efficacy on simulated industrial environments and food models. Another study described in this thesis investigated the antimicrobial effects of parsley and garlic on a range of mycobacteria species. Both studies used conventional microbiological methods such as plaque assays, AlamarBlue assay (MABA) and growth curves, …
